A's move to top of MLB Power Rankings; Blue Jays plummet

The first regular season edition of the TSN.ca MLB Power Rankings brings about plenty of change, now that regular season production has replaced offseason projection.

Coming out on top, at this early juncture, is the Oakland A's, who own a monstrous plus-33 run differential through their first 10 games.

Some other teams that have impressed early include the Atlanta Braves, Texas Rangers, Arizona Diamondbacks and Colorado Rockies, all of whom are ranked at least 10 spots higher than they were in the preseason and are all in the Top 10.

On the flip side of that coin, the Toronto Blue Jays may be the most disappointing team this early in the year. Ranked a lofty No. 3 in the preseason, the Blue Jays plummet to 27th as their revamped pitching staff hasn't been able to get anyone out.

Others ranked much lower in the season's first update include the L.A. Angels of Anaheim, Milwaukee Brewers and Tampa Bay Rays.
